Add tests, add user data, refactoring

[simonv3]

What's changed

• I've started adding a test framework (requires mocha) to run, cause I was doing some refactoring, and wasn't sure that things were still working.
• Add basic user data.
• Turn Beardo into a module that can be imported into other files.

@bnvk before merging this in, I'd love to hear your thoughts on the lay out of the user data, and also, if you could please test that everything still works the way that it should for you - I think Beardo does a couple of things that I don't use it for (or know how to use it for), so it'd be great to test those. This is why we need those tests!

Ex: I have no idea what Beardo.Trim is for.

@simonv3 merged that puppy in. I'll work on implementing your user profile and the unit tests more thoroughly soon. Danke :)
